25 years ago, fiber cement boards were introduced to the siding industry. Now architects and builders commonly use this siding choice because of its cost savings and wide variety of styles and options. When choosing a siding product most homeowners are concerned with:
DID YOU KNOW?
Did you know that the gaps in your fiber cement siding are left there on purpose. Although the material expands and contracts less than wood, best installation practices still allow for some movement and to respond to shifts in the home. Edge gaps are filled with caulk to prevent water damage and every siding butt joint should have flashing behind it to do the same. The flashing should be a non-discreet color so that it is barely noticeable. If there are significant gaps that are destroying the aesthetics of the siding (board too small to begin with, too large of expansion gaps) the best practice is to remove and replace, both for cosmetics and moisture prevention.
